I have removed and purged Eclipse using
apt-get remove eclipse
apt-get purge eclipse
After typing in
eclipse, I still get Eclipse splash screen. I waited for over five minutes to see if Eclipse will come up. It did not.
I went to GUI Add/ Remove software and found that Eclipse packages were still there. I marked them for removal and they were removed.
Terminal could not find Eclipse - good. There was no Eclipse under Programming menu - good.
In Terminal I did
apt-get install eclipse-cdt.
It installed and can be executed, but it takes forever to come up. Probably because both Java and CDT packages are being loaded.
BUT - all I got, again, Eclipse (platform) 3.8 !
I want the latest Eclipse Oxygen.
How do I accomplish that? (What repository is this ancient Eclipse 3.8 coming from?) Currently running Eclipse "checking for software" but that did not pan in past attempts.
